The inhabitants of Morrano have always called the formation "Peña Falconera" because according to tradition in this area falcons were bred, and "falcon" is the word's translation into the Aragonese language. Today the nickname "Falconero" is still used by the inhabitants of Morrano. A few years ago the stone was given a new name with the creation of the natural park. This name, "Huevo de Morrano" (Morrano egg), was created by a forester.[2] In Spanish, the name is "Alconera Peña," although that version is used much less frequently. The name "Peña los Pacos"[3] is also used.
